Overview
The Baer Brakes 4302484FR is an SS4 Plus Deep Stage rear brake kit in Fire Red for GM 10/12 bolt C-clip rear ends with C-clip eliminators in the housing ends. Two 4-piston S4 calipers clamp 11 inch two-piece slotted, drilled, zinc-plated vented rotors, and the system is sized for wheels 15 inch and larger.
Baer built the SS4 Plus Deep Stage as its first drag race system for heavy, fast cars that may also see street use. Each caliper uses 1.75 inch pistons in hard anodized aluminum with stainless steel abutments and noise suppression clips. The kit includes high friction pads for drag race applications, FMSI number DR1, and dust and weather seals. The HB100 pad type is also an option for this caliper.
Key features
- Two S4 calipers, each with four pistons, in Fire Red
- 1.75 inch pistons with hard anodized aluminum construction
- 11.0 inch vented, two-piece slotted, drilled and zinc-plated rotors
- Billet aluminum hats drilled for 5/8 inch wheel studs
- Rotors pre-assembled with NAS high grade stainless hardware
- Designed for wheels 15 inch and larger, manufactured in Phoenix, Az
Before you buy
Drag race brakes work hard in a short time. Heavy cars that run hard launches and then drive home generate a lot of heat, so pad compound matters as much as caliper size. Match the pad to how the car will be used. Race-only compounds often need heat to work well and can feel weak when cold, which makes them a poor choice for a daily driver. Think about the wheels, tires and other brake parts that will change once the rear is upgraded.
Front brakes should be matched to the rear so the car stops in a balanced way. Check master cylinder size, proportioning and brake line routing before the first run. Hoses and lines are often replaced at the same time as the rotors, since worn lines can swell under pressure.
- Check pad wear after each event
- Look for cracks around the slots and drill holes
- Re-check wheel studs and hardware after the first few runs

Vehicle fitment
The kit is built for rear axles with a GM 10/12 bolt C-clip flange in the small car pattern, a 5×4.50/5×4.75 wheel bolt pattern, and C-clip eliminators in the housing ends. Verify the year, model and trim fit before buying.
Axles that still use C-clips without eliminators are not covered by this kit. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Rotors come pre-assembled with NAS high grade stainless hardware, and mounting hardware is included. Because the kit requires C-clip eliminators, the housing ends must already have them before the rotors and calipers go on. Hoses are not included, so brake lines need to be sourced separately. Brake work is safety-critical, so have a qualified technician verify the installation.
What’s included
Two S4 calipers with 1.75 inch pistons, two pre-assembled 11.0 inch rotors, NAS high grade stainless hardware, mounting hardware and high friction drag race pads.
Not included: brake hoses and a park brake.
